This article is mis-titled. The ORNL project seems to be entirely about optimizing DNN hyperparameters (like Google's AutoML, I think), and not about inventing novel DNN architectures.
Worse, the work has absolutely nothing to do with Scientific Discovery, which is a difficult and hugely ambitious area of ML study which involves generating novel induction of necessary mechanisms, not just the mostly random generation and testing of plausible patterns against outcomes.
Unless a ML method proposes hypotheses that are based on the induction of novel mechanistic principles, it ain't discovery. It's mere trial and error.

“Scaled across Titan’s 18,688 Tesla GPUs, ”. I am sure that’s all Nvidia really cared about, they’d write anything that made their customers look smart.

Like most automated machine learning, this looks incredibly intensive/expensive computationally. I look forward to the day it's within reach for more researchers. Until then, it's a weird kind of news that has little impact on how most NNs get tuned.

However, I disagree about the lack of a connection between ORNL's work on MENNDL and scientific discovery. I'm going off of what ORNL told me, but according to them, using DL has been hard for scientists and this could make it easier. I am a writer, not an engineer, but here is how ORNL explains it: "Because scientific data often looks much different from the data used for animal photos and speech, developing the right artificial neural network can feel like an impossible guessing game for nonexperts. To expand the benefits of deep learning for science, researchers need new tools to build high-performing neural networks that don’t require specialized knowledge."

The math behind Gene Regulatory Networks is basically the same as that used in Neural Networks. Gene Regulatory Networks control cell state and cellular development (including neurogenesis) and we can see neurogenesis as natures way of using neural network technology (Gene Regulatory Networks) to build a higher level neural network technology (Neural Networks).

You are right about the 2015 publication. I believe ORNL waited until it had results from a user (Fermilab) to release the information.
There are also two related papers:
-- one is about the Fermilab's neutrino research using MENNDL http://ieeexplore.ieee.org/document/7966131/
-- and the other is about evolving deep neural nets in HPC:

Seems like these articles are becoming more common. Someone claims new meta-ai alg will change everything. In reality, just another team's hyper-param optimization setup.
Worse, the work has absolutely nothing to do with Scientific Discovery, which is a difficult and hugely ambitious area of ML study which involves generating novel induction of necessary mechanisms, not just the mostly random generation and testing of plausible patterns against outcomes.

I thought AI-applied-to-AI might be related to the work of Schmidhuber et al on self-improving search algorithms:

I don't know how to feel when things like this happen.
Their news release has more technical detail than I could put in my blog. https://www.ornl.gov/news/scaling-deep-learning-science
